bootstrapping manually when auto_bootstrap=false ?
I’m trying to figure out the best way to bootstrap our nodes.
I *think* I want our nodes to be manually bootstrapped. This way an admin
has to explicitly bring up the node in the cluster and I don’t have to
worry about a script accidentally provisioning new nodes.
The problem is HOW do you do it?
I couldn’t find any reference anywhere in the documentation.
I *think* I run nodetool repair? but it’s unclear..

I'd consider solving your root problem of "people are starting and stopping
servers in prod accidentally" instead of making Cassandra more difficult to
manage operationally.

why auto_bootstrap=false? The documentation even suggests the opposite. If
you don't auto_bootstrap the node will take queries before it has copies of
all the data, and you'll get the wrong answer (it'd not be unlike using CL
ONE when you've got a bunch of dropped mutations on a single node in the
cluster).

- In Cassandra yaml set auto_bootstrap = false
- Boot node
- nodetool rebuild
Very similar to

auto_bootstrap is orthogonal to joining or not joining the ring.
https://engineering.eventbrite.com/changing-the-ip-address-of-a-cassandra-node-with-auto_bootstrapfalse/
Explains why. Basically joining a node without bootstrapping just means it
gets a range but doesn't get streamed the data for that range. That's
almost never what you want, unless you're doing the above operation while
replacing a node.
I +1 that the real problem is nodes auto-starting cassandra, ever.
